Connecting to Sendmail

I can't connect to sendmail from a client. Is there a firewall
setting that should specifically open up a port (110 I think) or am I
doing somethin wrong on the client.

Server is RH 9.0 running sendmail...

Thanks
Peter

Normaly sendmail runs on port 25. (smtp)
you can try to connect to it using telnet: "telnet <IP-ADDRESS> 25"
on the host self, you can use "netstat -a" to see if sendmail is running.

Goodluck

Pat attention to 1) at the following post:
http://groups.google.com/groups?as_u...newsgroups.com

Rebuild the sendmail.cf file and restart sendmail after making the change to
sendmail.mc.

Also, get familiar with the FAQs. Your question has been answered many,
many, many times:

Port 110 is pop3, sending mail (smtp) is port 25 (/etc/services tells you
what service each port is for). Sendmail does not do pop3 (you need a
different daemon for that). Also by default sendmail in RH only listens
on localhost (127.0.0.1), unless you modified that. Check 'netstat -atn'
to see what IPs and ports are listening (0.0.0.0 means any IP). You might
also need to check /etc/hosts.allow, hosts.deny and firewall settings.

I ran telnet localhost 110 and it says;

Connected to localhost 127.0.0.1
+OK POP3 localhost.localdomain v2001.78rh server ready.

So, POP seems to be working, Kmail is setup and I can send emails but
when I reply from the client machine I can't receive emails back on
the server. What should I try next?

I can log on from a client machine via telnet on port 110 and check my
messages, so POP is up and running by default on RH 9.0.

I can send email from the server machine at command line and from
KMail but when I reply it doesn't show up at the server.

Why can't I receive incoming mail?
